Re: YafaRay rendering plug-in
wilx, gsnake69, I wouldn't be astonished that Apple decided to forbid to run some .dylib dynamic libraries imported in a sandboxed program. Does it work with the free version?

Re: YafaRay rendering plug-in
So it works on the free version... Is there a way to make it work in the "paid" MacStore version ? It's strange to have a feature working on a free version and not working on a paid version ...
Hi, guys! Can you tell me, why rendering with natural light is too dark? I've drawn a room with 4 walls, floor and ceil (17 sq.m). Placed simple double window. And a table inside (just for example). Placed virtual visitor and made yafaray render. (window to the NE side and 8AM - morning - very thin stripe of sunlight on the wall) Until I turn on ceil lighting images are very dark - almost black room with window and sunlight stripe! Sky lighting doesn't help. Only ceil lighting... What I do wrong? Or is it normal? I'm trying to compare with real life and my room with the same conditions is much lighter at morning. (yes, i know about aperture and shutter time in photography, but...) Can I setup renderer to make pics closer to real life with natural lighting?
I've tried AO and path tracing modes - same results...

Re: YafaRay rendering plug-in
Hi bam0o!
Aperture, shutter speed and ISO is what normally controls the exposure. Unfortunately none of these parameters can be controlled when making snapshots with the SH3D camera. So you will need to brighten your interior a bit by adding a few light sources. Two panel lights at low intensity, one covering the entire ceiling and facing downward with intensity 8, and one covering the entire floor and facing upwards with intensity 3, might create a better exposure. You may have to experiment a bit before getting it perfect.
Another thing: I have of course not seen your renders, so I don’t know how dark they really are.
The SH3D camera is an absolute observer, whilst our eyes are dynamic observers. So when your snapshot is viewed against a white background, your eyes are automatically adjusting the white balance and the light to the brightest area. Any normal exposure will seem a bit dark when viewed against a bright white light. Try viewing your renders against a dark background. Maybe they are not as dark as they appear.

Without additional light sources, an interior rendering is always dark.
If you want to have a natural rendering, you can use path tracing global illumination by increasing the number of light bounces if necessary. Turning on the sky lighting (without texture) can bring a little more brightness.
You can also add light panels as suggested ceciliabr by paying attention to the light power so that it stays close to reality.

Re: YafaRay rendering plug-in
Here's the version 1.4 of the YafaRay rendering plug-in. It includes the last version 3.5.1 of libYafaray with the small improvements that I previously programmed for YafaRay plug-in (better handling of images and memory errors). The plug-in is smaller this time (15.8 MB instead of 21 MB) because it doesn't need Boost and some other libraries anymore.
Under Windows, the plug-in should now work correctly if your login contains non ASCII letters (i.e. accentuated or non Latin letters). Under macOS, I signed the .dylib files in the hope it will fix some security issues. Not sure it will be enough for all cases, though...
